A．The I.Q. score gap between blacks and whites could not be eliminated.
B．The 15-point I. Q. gap was a result of miscalculation.

Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleep—when most vivid dreams occur—as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh, But not all parts of the brain are equally involved; the limbic system (the "emotional brain") is especially active, while the pre frontal cortex (the center of intellect and reasoning) is relatively quiet. "We wake up from dreams happy or depressed, and those feelings can stay with us all day", says Stanford sleep researcher Dr. William Dement.
The link between dreams and emotions shows up among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events—until, it appears, we begin to dream.
And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recur ring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.
At the end of the day, there's probably little reason to pay attention to our dreams at all unless they keep us from sleeping of "we wake up in a panic", Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people's anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep—or rather dream—on it and you'll feel better in the morning.
Researchers have come to believe that dreams ______.
A．can be modified in their courses
B．are susceptible to emotional changes
C．reflect our innermost desires and fears
D．are a random outcome of neural repairs
Dr. James A. Naismith, the father of basketball, was an instructor at a YMCA(基督教) Training school. The school trained people to work in YMCAs. Officials at the school were concerned about the low attendance during the winter months. They felt that people didn't attend then because the school did not have a good winter sports program. So they asked Dr. Naismith for help. He came up with a new indoor game.
Naismith studied current games. He found that all the most popular games used a ball. So a ball would be a part of his new game, he decided. But kicking the ball or hitting it would be too rough for indoor. So he put 2 peach baskets up on poles. The players had to try to throw a soccer ball into them. Naismith then made thirteen rules for the game. 12 of them are still in use today. Just 7 years after the game began, professional basketball teams were formed.
And that's how basketball was born.
Which of the following would be the best title for the passage？
A．The Birth of Basketball
B．YMCA and Basketball
C．Basketball——an Indoor Game
D．A Winter Sports Program
As part of the application procedure (手续) , Dr. Ginoux was asked to prepare a list of all the operations performed in the previous even years. Slowly, as she worked on the long list, she began to feel uncertain. She began to question some of her decisions. Had she used the best technique in that case？ Maybe, in this case, she should have given one more test before operating？ On the other hand, maybe she should have. . . Would the doctors on the selection committee understand that, as the only trained surgeon in the area, she usually could not get advice from others and therefore, had to rely completely on her own judgment？ For the first time, Dr. Ginoux felt lonely and isolated.
The longer Dr. Ginoux worked on the application forms, the more depressed she became. As hope faded, she wondered if a "country doctor"had a realistic chance of being accepted by the American College of Surgeons.
Dr. Ginoux was working in______.
A．a large city
B．the American College of Surgeons
C．an area far from any big city
D．a selective organization
Dr. Conrad and William C. Louis presented their initial findings in a talk yesterday at the Fermi National Accelerator Laboratory where the experiment is being performed.
The goal was to confirm or refute observations made in the 1990s in a Los Alamos experiment that observed transformations in the evanescent but bountiful particles known as neutrinos(微中子). Neutrinos have no electrical charge and almost no mass, but there are so many of them that they could collectively outweigh all the stars in the universe.
The new experiment has attracted wide interest. That reflected in part the hope of finding cracks in the Standard Model, which encapsulates physicists' current knowledge about fundamental particles and forces.
The Standard Model has proved remarkably effective and accurate, but it cannot answer some fundamental questions, like why the universe did not completely annihilate(毁灭) itself an instant after the Big Bang.
The birth of the universe 13.7 billion years ago created equal amounts of matter and antimatter. Since matter and antimatter annihilate each other when they come in contact, that would have left nothing to coalesce into stars and galaxies. There must be some imbalance in the laws of physics that led to a slight preponderance of matter over antimatter, and that extra bit of matter formed everything in the visible universe.
The imbalance, some physicists believe, may be hiding in the dynamics of neutrinos.
Neutrinos come in three known types, or flavors. And they can change flavor as they travel. But the neutrino transformations reported in the Los Alamos data do not fit the three-flavor model, suggesting four flavors of neutrinos, if not more.
The new experiment sought to count the number of times one flavor of neutrino, called a muon(μ介子), turned into another flavor, an electron neutrino.
For most of the neutrino energy range they looked at, the scientists did not see any more electron neutrinos than would be predicted by the Standard Model. That ruled out the simplest ways of interpreting the Los Alamos neutrino data, Dr. Conrad and Dr. Louis said.
But at the lower energies, the scientists did see more electron neutrinos than predicted: 369, rather than the predicted 273. That may simply mean that some calculations are off. Or it could point to a subtler interplay of particles, known and unknown.
Dr. Louis said he was surprised by the results". I was sort of expecting a clear excess or no excess", he said. "In a sense, we got both".
It can be inferred from Paragraph 1 that the" initial findings" of Dr. Conrad and Louis are ______.
A．a new class of subatoms.
B．new subatomic particles.
C．new characters of neutrinos.
D．none of the above.
Copying Birds May Save Aircraft Fuel
Both Boeing and Airbus have trumped the efficiency of their newest aircraft, the 787 and A350 respectively. Their clever designs and lightweight composites certainly make a difference. But a group of researchers at Stanford University, led by Ilan Kroo, has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use, and it would not require them to buy new aircraft.
The answer, says Dr Kroo, lies with birds. Since 1914, scientists have known that birds flying in formation-a V-shape-expand less energy. The air flowing over a bird's wings curls upwards behind the wingtips, a phenomenon known as upwash. Other birds flying in the upwash experience reduced drag, and spend less energy propelling themselves. Peter Lissaman, an aeronautics expert who was formerly at Caltech and the University of Southern California, has suggested that a formation of 25 birds might enjoy a range increase of 71%.
When applied to aircraft, the principles are not substantially different. Dr. Kroo and his team modelled what would happen if three passenger jets departing from Los Angeles, San Francisco and Las Vegas were to assemble over Utah, assume an inverted V-formation, occasionally change places so all could have a turn in the most favourable positions, and proceed to London. They found that the aircraft consumed as much as 15% less fuel (coupled with a reduction in carbon-dioxide output). Nitrogen-oxide emissions during the cruising portions of the flight fell by around a quarter.
There are, of course, knots to be worked out. One consideration is safety, or at least the perception of it. Would passengers feel comfortable travelling in companion？ Dr. Kroo points out that the aircraft could be separated by several nautical miles, and would not be in the intimate groupings favoured by display teams like the Red Arrows. A passenger peering out of the window might not even see the other planes. Whether the separation distances involved would satisfy air- traffic-control regulations is another matter, although a working group at the International Civil Aviation Organisation has included the possibility of formation flying in a blueprint for new operational guidelines.
It remains to be seen how weather conditions affect the air flows that make formation flight more efficient. In zones of increased turbulence, the planes' wakes will decay more quickly and the effect will diminish. Dr. Kroo says this is one of the areas his team will investigate further. It might also be hard for airlines to co-ordinate the departure times and destinations of passenger aircraft in a way that would allow them to gain from formation flight. Cargo aircraft, in contrast, might be easier to reschedule, as might routine military flights.
As it happens, America's armed forces are on the case already. Earlier this year the country's Defence Advanced Research Projects Agency announced plans to pay Boeing to investigate formation flight, though the programme has yet to begin. There are reports that some military aircraft flew in formation when they were low on fuel during the Second World War, but Dr. Lissaman says they are unsubstantiated. "My father was an RAF pilot and my cousin the skipper of a Lancaster lost over Berlin," he adds. So he should know.
Findings of the Stanford University researchers will promote the sales of new Boeing and Airbus aircraft.
A．Right
B．Wrong
It is a favorite pastime of older people to lament the defects of the young. Every generation seems to be convinced that in its day, standards were higher, schools were tougher and kids were smarter. But if I.Q. scores are any measure, and even their critics agree they measure something, people are getting smarter. Researchers who study intelligence say scores around the world have been increasing so fast that a high proportion of people regarded as normal at the turn of the century would be considered way below average by today's tests.
Psychologists offer a variety of possible explanations for the increase, including better nutrition, urbanization, more experience with test taking, and smaller families. Some even say that television and video games have made children's brains more agile. But no explanation is without its critics, and no one can say with certainty what effects, if any, the change is having on how people lead their daily lives. It is all the more mysterious because it seems to be happening in the absence of a simultaneous increase in scores on achievement tests. One explanation for the rise is ruled out: genetics. Because the increase has taken place in a relatively short period of time, it cannot be due to genetic factors.
The worldwide pattern of rising scores in industrialized nations was discovered by Dr. James R. Flynn, now a professor at the University of Otego, New Zealand. He began looking into the subject in the 1980's in an effort to rebut Dr. Arthur Jensen, the professor from the UC Berkeley who argued that even if the environments of blacks and whites were equalized, the 15-point gap in I. Q. scores between the races would only be partly eliminated.
As Dr. Flynn investigated, he found that I. Q. scores were going up almost everywhere he looked. Although the gap remains, Dr. Flynn said the movement in scores suggests that the gap need not be permanent. If blacks in 1995 had the same mean I. Q. that whites had in 1945, he said, it may be that the average black environment of 1995 was equivalent in quality to the average white environment of 1945. "Is that really so implausible？" Dr. Flynn asked.
Meanwhile, the kinds of intelligence that are promoted and respected vary from time to time, said Dr. Patricia Greenfield, a psychology professor at the UCLA. Playing computer games like Tetris promotes very different skills from reading novels. The new skills, she said, are manifested in the world. "Flynn will tell you we don't have more Mozarts and Beethovens," Dr. Greenfield said, "I say, look at the achievements of science, like DNA. Or look at all the technological developments of this century. "
The case of older people is mentioned to______.
A．illustrate the defects of young people
B．stress that standards of education are dropping
C．imply that young people are actually not more stupid than earlier generations
D．compare the intelligence gap between generations
In the study, when male subjects witnessed people they perceived as bad guys being stroke by a mild electrical shock, their M.R.I. scans lit up in primitive brain areas associated with reward. Their brains' empathy centers remained dull. Women watching the punishment, in contrast, showed no response in centers associated with pleasure. Even though they also said they did not like the bad guys, their empathy centers still quietly gloved.
The study seems to show for the first time in physical terms what many people probably assume they already know: that women are generally more empathetic than men, and that men, and that men take great pleasure in seeing revenge exacted. Men "expressed more desire for revenge and seemed to feel satisfaction when unfair people were given what they perceived as deserved physical punishment," said Dr. Tania Singer, the lead researcher, of the Wellcome Department of Imaging Neuroscience at University College London. But far from condemning the male impulse for retribution, Dr. Singer said it had an important social function: "This type of behavior. has probably been crucial in the evolution of society as the majority of people in a group are motivated to punish those who cheat on the rest."
The study is part of a growing body of research that is attempting to better understand behavior. and emotions by observing simultaneous physiological changes in the brain, a technique now attainable through imaging. "Imaging is still in its early days but we are transitioning from a descriptive to a more mechanistic type of study," said Dr. Klaas Enno Stephan, a co-author of the paper.
Dr. Singer's team was simply trying to see if the study subjects' degree of empathy correlated with how much they liked or disliked the person being punished. They had not set out to look into ** differences. To cultivate personal likes and dislikes in their 32 volunteers, they asked them to play a complex money strategy game, where both members of a pair would profit if both behaved cooperatively. The ranks of volunteers were infiltrated by actors told to play selfishly. Volunteers came quickly to "very much like" the partners who were cooperative, while disliking those who hided rewards, Dr. Stephan said. Effectively conditioned to like and dislike their game-playing partners, the 32 subjects were placed in scanners and asked to watch the various partners receive electrical shocks. On scans, both men and women seemed to feel the pain of partners they liked. But the real surprise came during scans when the subjects viewed the partners they disliked being shocked. "When women saw the shock, they still had an empathetic response, even though it was reduced," Dr. Stephan said. "The men had none at all." Furthermore, researchers found that the brain's pleasure centers lit up in males when just punishment was meted out.
The researchers cautioned that it was not clear if men and women are born with divergent responses to revenge or if their social experiences generate the responses. Dr. Singer said larger studies were needed to see if differing responses would be seen in cases involving revenge that did not involve pain. Still, she added, "This investigation would seem to indicate there is a predominant role for men in maintaining justice and issuing punishment."

A typical brain-teaser went like this. There are three light switches on the ground-floor wall of a three-storey house. Two of the switches do nothing, but one of them controls a bulb on the second floor. When you begin, the bulb is off. You can only make one visit to the second floor. How do you work out which switch is the one that controls the light？
This problem, or one equivalent to it, was presented on a computer screen to a volunteer when that volunteer pressed a button. The electrical activity of the volunteer’s brain (his brainwave pattern) was recorded by the EEG from the button’s press. Each volunteer was given 30 seconds to read the puzzle and another 60 to 90 seconds to solve it.
Some people worked it out; others did not. The significant point, though, was that the EEG predicted who would fall where. Those volunteers who went on to have an insight (in this case that on their one and only visit to the second floor they could use not just the light hut the heat produced by a bulb as evidence of an active switch) had had different brainwave activity from those who never got it. In the right frontal cortex, a part of the brain associated with shifting mental states, there was an increase in high-frequency gamma waves (those with 47-48 cycles a second). Moreover, the difference was noticeable up to eight seconds before the volunteer realised he had found the solution. Dr. Sheth thinks this may he capturing the “transformational thought” in action, before the brain’s “owner” is consciously aware of it.
This finding poses fascinating questions about how the brain really works. Conscious thought, it seems, does not solve problems. Instead, unconscious processing happens in the background and only delivers the answer to consciousness once it has been arrived at. Food for further thought, indeed.
Which kind of problems can he used in Dr. Bhattacharya and Dr. Sheth’s research？
A．Theoretical brain-teasing problems,
B．Simple but rarely known problems.
C．Puzzling hut realistic problems.
D．Simple but theoretical problems.
It's been some 50 years since the physicist-turned-novelist C. P. Snow delivered his famous "Two Cultures" lecture at the University of Cambridge, in which he decried the "gulf of mutual incomprehension", the "hostility and dislike" that divided the world's "natural scientists", its chemists, engineers, physicists and biologists, from its "literary intellectuals", a group that, by Snow's reckoning, included pretty much everyone who wasn't a scientist. His critique set off a frenzy of desperation that continues to this day, particularly'in the United States, as educators, policymakers and other observers lament the Balkanization of knowledge, the scientific illiteracy of the general public and the chronic academic turf wars that are all too easily lampooned.
Yet a few scholars believe that the cultural chasm can be bridged and the sciences and the humanities united into a powerful new discipline that would apply the strengths of both mindsets, the quantitative and qualitative, to a wide array of problems. Among the most ambitious of these exercises in fusion thinking is a program under development at Binghamton University in New York called the New Humanities Initiative.
Jointly conceived by David Sloan Wilson, a professor of biology, and Leslie Heywood, a professor of English, the program is intended to build on some of the themes explored in Dr. Wilson's evolutionary studies program, which has proved enormously popular with science and nonscience majors alike, and which he describes in the recently published "Evolution for Everyone". In Dr. Wilson's view, evolutionary biology is a discipline that, to be done right, demands a crossover approach, the capacity to think in narrative and abstract terms simultaneously, so why not use it as a template for emulsifying the two cultures generally？ "There are more similarities than differences between the humanities and the sciences, and some of the stereotypes have to be altered," Dr. Wilson said, "Darwin, for example, established his entire evolutionary theory on the basis of his observations of natural history, and most of that information was qualitative, not quantitative. "
As he and Dr. Heywood envision the program, courses under the New Humanities rubric would be offered campus-wide, in any number of departments, including history, literature, philosophy, sociology, law and business. The students would be introduced to basic scientific tools like statistics and experimental design and to liberal arts staples like the importance of analyzing specific texts or documents closely, identifying their animating ideas and comparing them with the texts of other immortal minds.

A．posing a contrast
